[ruby-core:120177] [Ruby master Misc#20944] Module#set_temporary_name(nil) doesn't remove completely effect of a previous assigning a temporary name

Issue #20944 has been reported by andrykonchin (Andrew Konchin). ---------------------------------------- Misc #20944: Module#set_temporary_name(nil) doesn't remove completely effect of a previous assigning a temporary name https://bugs.ruby-lang.org/issues/20944 * Author: andrykonchin (Andrew Konchin) * Status: Open ---------------------------------------- The method Module#set_temporary_name` was introduced in Ruby 3.3. I've noticed a surprising behaviour when a temporary name is assigned to an anonymous module (that has nested non-anonymous modules) and then `Module#set_temporary_name` called with `nil`. The name of the nested module initially was fully qualified (e.g. `#<Module:0x000000010cc5a280>::N`) but after `set_temporary_name(nil)` call it becomes `nil`. Example (from ruby/spec): ```ruby m = Module.new module m::N; end m::N.name # => #<Module:0x...>::N m::N.set_temporary_name("fake_name") m::N.name # => "fake_name" m::N.set_temporary_name(nil) m::N.name # => nil <==== quesitonable behaviour ``` I would expect a nested module name to have the initial value `#<Module:0x000000010cc5a280>::N` at the end. The documentation states: > If the given name is nil, the module becomes anonymous again. So I would expect all the effects of setting a (non-nil) temporary name should be also rolled back.

I have managed to reproduce at least one instance that happens when there are hard memory limits. ```ruby #!/usr/bin/env -S RUBYOPT="--disable-gems" ruby -v s = "\x04\b#{"{\x06" * 100}i\x01".b.freeze

begin Marshal.load(s) rescue ArgumentError => e es[i += 1] = e end end ``` Backtrace from gdb on `rb_bug`: ``` #0 rb_bug (fmt=fmt@entry=0xfffff7dd9588 "object allocation during garbage collection

Issue #20904 has been reported by jun66j5 (Jun Omae). ---------------------------------------- Bug #20904: 3.4.0-preview2: Building miniruby.exe fails for mswin32 https://bugs.ruby-lang.org/issues/20904 * Author: jun66j5 (Jun Omae) * Status: Open * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- I tried to build 3.4.0-preview2 with MSVC x86, however linking miniruby.exe failed with the following eror: ``` linking miniruby.exe Creating library miniruby.lib and object miniruby.exp win32.obj : error LNK2019: unresolved external symbol _GetSystemTimePreciseAsFileTime referenced in function _clock_gettime miniruby.exe : fatal error LNK1120: 1 unresolved externals ``` It doesn't fail with MSVC x64. Investigating it, Windows 8 is required after #20563 but `NTVER` is still `0x0600` in `win32/Makefile.sub`. I think it should be `0x0602`. Workaround is to invoke `win32\configure.bat` with `--with-ntver=0x0602`. Also, adding temporarily `-w24013` to `WARNFLAGS` in `win32/Makefile.sub`, the following warning is received. ``` compiling win32/win32.c win32.c win32/win32.c(4789): warning C4013: 'GetSystemTimePreciseAsFileTime' undefined; assuming extern returning int ``` -- https://bugs.ruby-lang.org/

Issue #20938 has been reported by eightbitraptor (Matt V-H). ---------------------------------------- Bug #20938: Percent String literal delimiter impacts string contents with parse.y https://bugs.ruby-lang.org/issues/20938 * Author: eightbitraptor (Matt V-H) * Status: Open * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- The following code defines 2 programs that declare string literals using `%` and a single byte delimiter. I'd expect these programs to have the same output no matter which delimiter is used. With Prism, both programs output the same value (the string content: `1_\n`), but using parse.y the output values differ depending on the delimiter. Are the outputs supposed to be the same or different? ``` program1 = "%\n1_\r\n\n" # => parse.y: 1_, prism: "1_\n" program2 = "%'1_\r\n'" # => "1_\n" p eval(program1) p eval(program2) ``` -- https://bugs.ruby-lang.org/

[ruby-core:119442] [Ruby master Feature#20782] Introduction of Happy Eyeballs Version 2 (RFC8305) in TCPSocket.new
by shioimm (Misaki Shioi) 10 Dec '24

10 Dec '24

Issue #20782 has been reported by shioimm (Misaki Shioi). ---------------------------------------- Feature #20782: Introduction of Happy Eyeballs Version 2 (RFC8305) in TCPSocket.new https://bugs.ruby-lang.org/issues/20782 * Author: shioimm (Misaki Shioi) * Status: Open ---------------------------------------- This is an implementation of Happy Eyeballs version 2 (RFC 8305) in `TCPSocket.new`. See https://github.com/ruby/ruby/pull/11653 ### Background Prior to this implementation, I implemented Happy Eyeballs Version 2 (HEv2) for `Socket.tcp` in https://github.com/ruby/ruby/pull/9374. HEv2 is an algorithm defined in [RFC 8305](https://datatracker.ietf.org/doc/html/rfc8305), aimed at improving network connectivity. For more details on the specific cases that HEv2 helps, please refer to https://bugs.ruby-lang.org/issues/20108. ### Proposal & Outcome This proposal implements the same HEv2 algorithm in `TCPSocket.new`. Since `TCPSocket.new` is used more widely than `Socket.tcp`, this change is expected to broaden the impact of HEv2's benefits. Like `Socket.tcp`, I have also added `fast_fallback` keyword argument to `TCPSocket.new`. This option is set to true by default, enabling the HEv2 functionality. However, users can explicitly set it to false to disable HEv2 and use the previous behavior of `TCPSocket.new`. It should be noted that HEv2 is enabled only in environments where pthreads are available. This specification follows the approach taken in https://bugs.ruby-lang.org/issues/19965, where name resolution can be interrupted. (In environments where pthreads are not available, the `fast_fallback` option is ignored.) ### Performance Below is the benchmark of 100 requests to `www.ruby-lang.org` with the fast_fallback option set to true and false, respectively. While there is a slight performance degradation when HEv2 is enabled, the degradation is smaller compared to that seen in `Socket.tcp` . ```ruby require 'socket' require 'benchmark' hostname = "www.ruby-lang.org" port = 80 n = 100 Benchmark.bmbm do |x| x.report("fast_fallback: true") do n.times { TCPSocket.new(hostname, port).close } end x.report("fast_fallback: false") do n.times { TCPSocket.new(hostname, port, fast_fallback: false).close } end end ``` ``` ~/s/build ❯❯❯ ../install/bin/ruby ../ruby/test.rb Rehearsal -------------------------------------------------------- fast_fallback: true 0.017588 0.097045 0.114633 ( 1.460664) fast_fallback: false 0.014033 0.078984 0.093017 ( 1.413951) ----------------------------------------------- total: 0.207650sec user system total real fast_fallback: true 0.020891 0.124054 0.144945 ( 1.473816) fast_fallback: false 0.018392 0.110852 0.129244 ( 1.466014) ``` -- https://bugs.ruby-lang.org/

All decisions should be done at the bug tracker. - Dev meeting is a place we can ask Matz, nobu, nurse and other developers directly. - Matz is a very busy person. Take this opportunity to ask him. If you can not attend, other attendees can ask instead of you (if attendees can understand your issue). - We will write a record of the discussion in the file or to each ticket in English. - All activities are best-effort (keep in mind that most of us are volunteer developers). - The date, time and place of the meeting are scheduled according to when/where we can reserve Matz's time. - *DO NOT* discuss then on this ticket, please. # Call for agenda items If you have a ticket that you want matz and committers to discuss, please post it into this ticket in the following format: ``` * [Ticket ref] Ticket title (your name) * Comment (A summary of the ticket, why you put this ticket here, what point should be discussed, etc.) ``` Example: ``` * [Feature #14609] `Kernel#p` without args shows the receiver (ko1) * I feel this feature is very useful and some people say :+1: so let discuss this feature. ``` - It is recommended to add a comment by 2024/12/09. We hold a preparatory meeting to create an agenda a few days before the dev-meeting. - The format is strict. We'll use [this script to automatically create an markdown-style agenda](https://gist.github.com/mame/b0390509ce1491b43610b9ebb665eb86). We may ignore a comment that does not follow the format. - Your comment is mandatory. We cannot read all discussion of the ticket in a limited time. We appreciate it if you could write a short summary and update from a previous discussion. -- https://bugs.ruby-lang.org/

[ruby-core:120132] [Ruby master Misc#16124] Let the transient heap belong to objspace
by ko1 (Koichi Sasada) 08 Dec '24

Issue #16124 has been updated by ko1 (Koichi Sasada). Status changed from Assigned to Rejected transient heap was removed. ---------------------------------------- Misc #16124: Let the transient heap belong to objspace https://bugs.ruby-lang.org/issues/16124#change-110882 * Author: methodmissing (Lourens Naudé) * Status: Rejected * Assignee: ko1 (Koichi Sasada) ---------------------------------------- As per comment from Nobu in https://github.com/ruby/ruby/pull/2303#issuecomment-523248875 , I took an initial stab @ a tighter integration between objspace and the transient heap in https://github.com/ruby/ruby/pull/2400 ### Benefits * Multi-VM (MVM) friendly - ( vm -> objspace -> theap ) * The 32MB (current size) arena lazy allocated on ruby init is now properly freed on shutdown as well * It feels strange that the evacuation from the current global theap is to objspace, whereas the space evacuated from is a global arena. ### Not so great * A fast reference to a global variable `global_transient_heap` becomes a function call to `rb_objspace_get_theap()` and related pointer chasing from vm -> objspace -> theap * Some internal transient heap structs moved to the header file now leaks into all other reference sites where this source file (`transient_heap.c`) as previously just used for API * I'm not sure exactly of the boundary Koichi had in mind for the GC compile module and how tightly it should (or shouldn't) be coupled to the transient heap. `struct rb_objspace*` declarations elsewhere for example reveals nothing about the structure members for example, whereas with this PR a lot of transient heap internals are exposed via the header file now * Also possible to move `transient_heap.c` into `gc.c` - I feel theap is not an experimental feature anymore and has been stable for quite some time with plausible performance benefits. The downside of that is `gc.c` is quite dense already, but then all ruby heap management concerns belong to one compile unit. In a similar vein the global method cache could perhaps belong to the VM instance as well, effectively better alignment with MVM and also easier to have a balanced VM setup and teardown sequence without anything left dangling on ruby shutdown. Thoughts? -- https://bugs.ruby-lang.org/

[ruby-core:120120] [Ruby master Bug#20933] Unexpected IO::Buffer::MaskError in IO::Buffer#xor!
by agitter (Alexander Gitter) 07 Dec '24

Issue #20933 has been reported by agitter (Alexander Gitter). ---------------------------------------- Bug #20933: Unexpected IO::Buffer::MaskError in IO::Buffer#xor! https://bugs.ruby-lang.org/issues/20933 * Author: agitter (Alexander Gitter) * Status: Open * ruby -v: ruby 3.4.0dev (2024-12-06T12:47:35Z master 78614ee900) +PRISM [x86_64-linux] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- The following script raises `Mask overlaps source buffer! (IO::Buffer::MaskError)` most of the time when running it on my Ubuntu 24.04 machine. "Most of the time" means this sometimes (20% - 30%) works without issue. ```ruby a = IO::Buffer.new(1024 * 1024) b = IO::Buffer.new(1024 * 1024) a = IO::Buffer.new(1024 * 1024) # Removing this line makes this work much more reliably a.xor!(b) ``` I'm guessing this is somehow related to these being `MAPPED` buffers - reducing the sizes to 1024 bytes also fixes the problem. -- https://bugs.ruby-lang.org/
